Study Description

Brief Summary:

Both XueZhiKang and Statins are cholesterol-lowering medications that are often prescribed for individuals with high cholesterol and who are at risk for cardiovascular disease (CVD). Several studies, including one randomized, double-blind, placebo-controlled clinical trial, have suggested that the use of statins is more frequently associated with fatigue. And XueZhiKang may be not. The purpose of this study is to compare the effect of these two medications on fatigue in persons who are at moderate to low CVD risk based on the risk estimation system in ESC(European Society of Cardiology)/ESA(European Atherosclerosis Society) guidelines (2011) for the management of dyslipidemias.

Condition or disease	Intervention/treatment	Phase
Dyslipidemias	Drug: XueZhiKang; Drug: simvastatin	Phase 4

Detailed Description:

Individuals at risk for cardiovascular disease (CVD) are often prescribed statins, which are medications that reduce the amount of cholesterol in the blood. By lowering cholesterol levels, these individuals have a lower incidence of coronary artery disease, ischemic stroke, and peripheral arterial disease and so on. While statins are effective at lowering cholesterol levels, their effect on fatigue is obvious and has been suggested by several studies, including one randomized, double-blind, placebo-controlled clinical trial. And XueZhiKang may be not. The purpose of this study is to compare the effect of these two medications on fatigue in persons who are at moderate to low CVD risk based on the risk estimation system in ESC(European Society of Cardiology)/ESA(European Atherosclerosis Society) guidelines (2011) for the management of dyslipidemias.

This study will enroll individuals who do not currently take cholesterol-lowering medications. Participants will be randomly assigned to receive 600mg of XueZhiKang twice a day, or 20mg of simvastatin daily for 4 weeks. Study visits will occur at baseline and Week 4. Blood will be collected for laboratory testing, and standardized psychological questionnaires will assess fatigue scores and physical activity levels at baseline and week 4. Pill count will be used to assess adherence of XueZhiKang and simvastatin treatment at week 4. At week 4, medication side effects will be monitored and tests of alanine aminotransferase (ALT), aspartate aminotransaminase (AST) and creatine phosphate kinase (CPK) will be performed. At week 4, medication efficacy will be assessed and test of low-density lipoprotein cholesterol (LDL-C) will be performed.

Outcome Measures

Primary Outcome Measures :

1. Comparison Between XueZhiKang and Simvastatin on Fatigue Scores [ Time Frame: Measured at baseline and week 4 ]
   At baseline and week 4, the fatigue score was assessed by a fatigue questionnaire named as Fatigue Assessment Scale (FAS) which used 10-item fatigue measure with the fatigue score ranged from 10-50. The higher score was meaning of higher level of fatigue.

Secondary Outcome Measures :

1. Treatment Efficacy [ Time Frame: Measured at baseline and week 4 ]
   Treatment efficacy was estimated on the basis of triglyceride (TG), total cholesterol (TC), high-density lipoprotein-cholesterol (HDL-C), as well as LDL-C levels obtained at baseline and week 4.

Other Outcome Measures:

1. Comparison of XueZhiKang With Simvastatin of Physical Activity Level [ Time Frame: Measured at baseline and week 4 ]
   At baseline and week 4, we estimated physical activity level by short version of international physical activity questionnaire (IPAQ) with categorical score ranged from low to high. The higher score was meaning of lower physical activity level.
2. Comparison of Safety Laboratory Testings (ALT,AST,CPK) Between Simvastatin- and Xuezhikang-groups [ Time Frame: Measured at baseline and week 4 ]
   Fasting blood samples were collected at weeks 0 (randomization) and 4 (end of study) for clinical chemistry.
3. Comparison of Safety Laboratory Testing (Cr) Between Simvastatin- and Xuezhikang-group [ Time Frame: Measured at baseline and week 4 ]
   Fasting blood samples were collected at weeks 0 (randomization) and 4 (end of study) for clinical chemistry.
4. Treatment Adherence at Week 4 in Simvastatin- and Xuezhikang-group [ Time Frame: Measured at baseline and week 4 ]
   We counted the total number of pills that were dispensed to the participants at baseline and the total number of pills that were taken by participants at week 4.
